Abstract:
Objective The effects of flight factors on dog and rats are observed to acumulate the elementary data and experiences for space biology research and development of life support systems.It will be the first basic step for manned space flight in future.Methods Female dogs,Xiao-Bao and Shan-Shan were on board of two Model T-7A(S2)rockets separately.Duration of flight was about 25 min and height about 70 km.Four physiological parameters:electrocardiogram,blood pressure,breath and skin temperature were recorded.Results Both of two dogs returned safely and healthy.The physiological parameters of Xiao-Bao were successfully recorded on the first rocket.On the second one,partial data of Shan-Shan were interfered by the strong vibration during the separation of rocket body and cone.The obvious changes of heart rate,ECG and blood pressure were recorded for Xio-Bao to be affected by the effects of hyper-gravity and microgravity factors.These changes were normal,temporal and reversible physiological stress responses.Conclusion The dog can tolerate the action of variable factors during the T-7A(S2)flight and no pathological after-effects were observed.
